Final Answer :
E
Explanation :
Cnidarians are known for having ciliated larvae, a polyp form, a jellylike matrix (mesoglea), and nematocysts (stinging cells). A pharynx is not a characteristic specifically associated with cnidarians, as it is a feature found in various animal groups for the passage of food.
